  • New Methodology for Complete Properties Extraction from Simulation Traces
           Guided with Static Analysis
    • Authors: Mohamed Hanafy; Hazem Said; Ayman M. Wahba
      Abstract: This paper introduces a new methodology for digital design properties extraction from simulation traces. A new Breadth-First Decision Tree (BF-DT) mining algorithm is proposed for complete properties extraction from simulation traces. The new mining engine supports both bit-level and word-level values of different design variables. Static analysis technique is implemented to extract all data dependencies between the digital design variables. New traces regeneration algorithm is proposed to obtain reduced traces for more efficient and easier mining. The mining engine is guided with these data dependencies to extract complete design properties relating target variables desired to extract properties for and their cone of interest feature variables. The contributed mining technique has been tested for different designs with different sizes. The design properties generated from the mining engine completely match with all design properties covered in the input simulation traces. Moreover, the generated properties are at the highest possible level of abstraction leading to the best coverage for the input data space. The simulation results show that the proposed methodology has superior efficiency in extracting both bit-level and word-level complete assertions of digital design in both superior quality and feasible time.

  • Four-Port Network Parameters Extraction Method for Partially Depleted SOI
           with Body-Contact Structure
    • Authors: Jun Liu; Yu Ping Huang; Kai Lu
      Abstract: Abstract This work presents a model parameter extraction method based on four-port network for RF SOI MOSFET modeling. The gate, drain, source and body terminals are served as four separate ports. Four-port measurement simplifies the determination of small-signal equivalent circuit model elements such as parameters related to the body terminal which become clear in the equivalent circuit analysis. The extraction method of the RF SOI MOSFET extrinsic parasitic elements was also presented. The accuracy of the model extraction was verified by measurement and simulation from 100 MHz to 20 GHz.

  • A Routability-Aware Algorithm for Both Global and Local Interconnect
           Resource Test and Diagnosis of Xilinx SRAM-FPGAs
    • Authors: Aiwu Ruan; Haiyang Huang; Jingwu Wang; Yifan Zhao
      Abstract: Abstract With increasing scale of Field Programmable Gate Arrays (FPGAs), architecture of interconnect resources (IRs) in FPGA is becoming more and more complicated. IR testing plays an important role to guarantee correct functionality of FPGAs. Usually, architecture of Global IRs is regular, while architecture of Local IRs is more complicated compared to Global IRs. In the paper, a generic IR model revealing the connection relationships for both Global and Local IRs in Xilinx series FPGAs is studied. A routability-aware algorithm based on the generic IR model is also presented. Test configurations (TCs) can be automatically generated by the proposed algorithm. Thus, both Global and Local IRs can be tested with identical method. Further, the algorithm is generic and independent of type and size of FPGAs. The algorithm is evaluated in Virtex series FPGAs. Experimental results demonstrate that the routing algorithm is applicable to Virtex series FPGAs with higher IR coverage achieved.

  • Instruction-Vulnerability-Factor-Based Reliability Analysis Model for
           Program Memory
    • Authors: Qingyu Chen; Li Chen; Haibin Wang; Longsheng Wu; Yuanqing Li; Xing Zhao; Mo Chen
      Abstract: Abstract Bit faults induced by single-event upsets in instruction may not cause a system to experience an error. The instruction vulnerability factor (IVF) is first defined to quantify the effect of non-effective upsets on program reliability in this paper; and the mean time to failure (MTTF) model of program memory is then derived based on IVF. Further analysis of MTTF model concludes that the MTTF of program memory using error correcting code (ECC) and scrubbing is not always better than unhardened program memory. The constraints that should be met upon utilizing ECC and scrubbing in program memory are presented for the first time, to the best of authors’ knowledge. Additionally, the proposed models and conclusions are validated by Monte Carlo simulations in MATLAB. These results show that the proposed models have a good accuracy and their margin of error is less than 3 % compared with MATLAB simulation results. It should be highlighted that our conclusions may be used to contribute to selecting the optimal fault-tolerant technique to harden the program memory.

  • Mahalanobis Distance Based Approach for Anomaly Detection of Analog
           Filters Using Frequency Features and Parzen Window Density Estimation
    • Authors: Zewen Hu; Mingqing Xiao; Lei Zhang; Shuai Liu; Yawei Ge
      Abstract: Abstract Analog filters play a very important role in insuring the availability of electronic systems. Early detection of anomalies of analog filters can prevent the impending failures and enhance reliability. The complex architecture and the tolerances of multiple components make it very difficult to detect anomalies in analog filters. To address this concern, A Mahalanobis distance (MD) based anomaly detection method for analog filters is proposed in this paper. The conventional frequency features and the moment of frequency response are selected as the feature vector. Mahalanobis distance is used to transform the frequency feature vector to one dimensional MD data. The anomaly detection threshold is obtained based on probability density of the health MD data sets which is estimated by Parzen window density estimation method. The efficiency of the proposed method has been verified by two case studies. In the case studies, a comprehensive indicator constructed by miss alarm and false alarm is used to obtain an optimal anomaly detection threshold. One class SVM (OCSVM) based anomaly detection method is used as a comparison with our approach. The results illustrate that: (1) the proposed frequency features can effectively clarify the degradation of analog filters; (2) the proposed MD based approach can detect anomalies in analog filters effectively at an early time stage. (3) the proposed MD based approach can detect anomalies in analog filters more accurately than OCSVM based method.

  • Analog Circuit Test Point Selection Incorporating Discretization-Based
           Fuzzification and Extended Fault Dictionary to Handle Component Tolerances
    • Authors: Yiqian Cui; Junyou Shi; Zili Wang
      Abstract: Analog circuit test point selection aims to find the least number of test points that can isolate all the fault modes (including the fault-free case). The fault dictionary, which uses the integer-valued codes to represent the diagnosability of a specific test point, is very popular and saves computation efforts. However, the classical fault dictionary has a limited ability to handle the component tolerances and continuous-valued monitoring variables. To solve the problem, the approach of clustering-based discretization (CBD) is used to abstract the information of data samples distribution. We also develop a new fault dictionary construction technique called extended fault dictionary (EFD). An element of EFD is a set containing either a single integer code or multiple integer codes. The fault isolation rules are redefined, and a novel entropy measure is created in line with CBD of the continuous values. The practical test point selection procedures are presented, which avoids the likelihood to include a redundant test point. Finally, two application studies of circuit test point election are presented, showing that the proposed method provides an effective implementation option for the engineering practice of circuit diagnosis.

  • Optimal Selective Count Compatible Runlength Encoding for SOC Test Data
    • Authors: Harpreet Vohra; Amardeep Singh
      Abstract: Abstract Test data volume amount is increased multi-fold due to the need of quality assurance of various parts of the circuit design at deep submicron level. Huge memory is required to store this enormous test data which not only increases the cost of the ATE but also the test application time. This paper presents an optimal selective count compatible run length (OSCCPRL) encoding scheme for achieving maximum compression for reduction of the test cost. OSCCPRL is a hybrid technique that amalgamates the benefits of other two techniques: 10 Coded run length (10 C) and Selective CCPRL (SCCPRL) proposed here. These techniques work on improvement of the 9 C and CCPRL techniques. In OSCCPRL, entire data is segmented in blocks and further compressed using inter block and intra block level merging techniques. SCCPRL technique is used for encoding the compatible blocks while the 10C is used to do encoding at sub block (half block length) level. In case, if no compatibility is found at block/sub block level then the unique pattern is held as such in the encoded data along with the necessary categorization bits. The decompression architecture is described and it is shown how by just the addition of few states of FSM, better test data compression can be achieved as compared to previous schemes. The simulation results performed for various ISCAS benchmarks circuits prove that the proposed OSCCPRL technique provides an average compression efficiency of around 80 %.

  • An Effective Power-Aware At-Speed Test Methodology for IP Qualification
           and Characterization
    • Authors: Kapil Juneja; Darayus Adil Patel; Rajesh Kumar Immadi; Balwant Singh; Sylvie Naudet; Pankaj Agarwal; Arnaud Virazel; Patrick Girard
      Abstract: Abstract Advanced nanometer technologies have led to a drastic increase in operational frequencies resulting in the performance of circuits becoming increasingly vulnerable to timing variations. The increasing process spread in advanced nanometer nodes poses considerable challenges in predicting post-fabrication silicon performance from timing models. Thus, there is a great need to qualify basic building structures on silicon in terms of critical parameters before they could be integrated within a complex System-on-Chip (SoC). The work of this paper presents a configurable circuit and an associated power-aware at-speed test methodology for the purpose of qualifying basic standard cells and complex IP structures to detect the presence of timing faults. Our design has been embedded within test-chips used for the development of the 28 nm Fully Depleted Silicon On Insulator (FD-SOI) technology node. The relevant silicon results and analysis validate the proposed power-aware test methodology for qualification and characterization of IPs and provide deeper insights for process improvements.

  • Test Data Compression for System-on-chip using Flexible Runs-aware PRL
    • Authors: Haiying Yuan; Zijian Ju; Xun Sun; Kun Guo; Xiuyu Wang
      Abstract: Abstract This paper presents a flexible runs-aware PRL coding method whose coding algorithm is simple and easy to implement. The internal 2-n -PRL coding iteratively codes 2 n runs of compatible or inversely compatible patterns inside a single segment. The external N-PRL coding iteratively codes flexible runs of compatible or inversely compatible segments across multiple segments. The decoder architecture is concise. The benchmark circuits verify the flexible runs-aware PRL coding method, the experimental results show it obtains higher compression ratio and shorter test application time.

  • A Novel Approach for Diagnosis of Analog Circuit Fault by Using GMKL-SVM
           and PSO
    • Abstract: Abstract This paper presents a novel analog circuit fault diagnosis approach using generalized multiple kernel learning-support vector machine (GMKL-SVM) method and particle swarm optimization (PSO) algorithm. First, the wavelet coefficients’ energies of impulse responses are generated as features. Then, a diagnosis model is constructed by using GMKL-SVM method based on features. Meanwhile, the PSO algorithm yields parameters for the GMKL-SVM method. Sallen-Key bandpass filter and two-stage four-op-amp biquad lowpass filter fault diagnosis simulations are given to demonstrate the proposed diagnose procedure, and the comparison simulations reveal that the proposed approach has higher diagnosis precision than the referenced methods.

  • Analyzing Vulnerability of Asynchronous Pipeline to Soft Errors:
           Leveraging Formal Verification
    • Abstract: Abstract Glitches due to the secondary neutron particles from cosmic rays cause soft errors in integrated circuits (IC) that are becoming a major threat in modern sub 45nm ICs. Therefore, researchers have developed many techniques to mitigate the soft errors and some of them utilize the built in error detection schemes of low-power asynchronous null conventional logic (NCL). However, it requires extensive simulations and emulations for careful and complete analysis of the design, which can be costly, time consuming and cannot encompass all the possible input conditions. In this paper, we propose a framework to improve the soft error tolerant asynchronous pipelines by identifying and formally analyzing the vulnerable paths using the nuXmv model checker. The proposed framework translates the design behavior and specification into a state-space model and the potential vulnerabilities against soft errors in the pipeline as linear temporal logical (LTL) properties. These formally specified properties are then verified on the state-space model and in case of failure counterexamples are obtained. These counterexamples can then be further analyzed to obtain the soft error propagation paths and thus give insights about soft error tolerant approaches to the designers. For illustration, this work provides an analysis and comparison of three state-of-the-art asynchronous pipelines. Formal model and analysis of all the pipelines show that the soft error hardened pipeline is comparatively superior against soft errors but at the expense of almost two times area overhead.

  • A Novel Compact Model for On-Chip Vertically-Coiled Spiral Inductors
    • Authors: Bing Hou; Tong Liu; Jun Liu; Junli Chen; Faxin Yu; Wenbo Wang
      Abstract: Abstract A novel compact model for on-chip vertically coiled spiral inductors is presented. The vertical metal coils are modeled by a ladder network consisting of ideal inductors and resistors. The skin and proximity effects are taken into consideration. The capacitive parasitics between relevant metal layers are modeled. A method to analytically extract the model parameters is proposed. The model prediction shows excellent agreement between the data from both simulation and measurement over the frequency range of 0.1–66.1 GHz, for a vertically coiled spiral inductor manufactured in TSMC 90 nm RF CMOS technology.

  • Path Clustering for Test Pattern Reduction of Variation-Aware Adaptive
           Path Delay Testing
    • Authors: Michihiro Shintani; Takumi Uezono; Kazumi Hatayama; Kazuya Masu; Takashi Sato
      Abstract: Abstract In this study, a novel path clustering technique for adaptive path delay testing, where the test paths are altered according to the extracted device parameters, is proposed. The proposed algorithm is based on the k-means++ algorithm. By considering the probability function of the die-to-die systematic process variation, the proposed algorithm clusters path sets to minimize the total number of test paths. A figure of merit for clustering, which represents the expected number of test paths, is also proposed for quantitatively evaluating path clustering under different conditions. The proposed clustering method is evaluated numerically by applying it to the OpenCores benchmark circuit. Using our clustering technique, the average number of test paths in the adaptive test is reduced to less than 92 % compared with those in the conventional test. In addition, adaptive testing using the proposed technique can reduce the test patterns by 94.26 % while retaining the test quality.

  • CPP-ATPG: A Circular Pipeline Processing Based Deterministic Parallel Test
           Pattern Generator
    • Authors: Kuen-Wei Yeh; Jiun-Lang Huang; Laung-Terng Wang
      Abstract: Abstract Parallel computing is widely utilized to speed up automatic test pattern generation (ATPG); however, most of today’s parallel ATPGs are non-deterministic, which often leads to non-reproducible test pattern sets. This paper presents a fault-parallel test pattern generator: CPP-ATPG; it generates the same test pattern set regardless of the thread count and timing. Besides, it exhibits good speedup scalability as the thread count increases. These are achieved by the circular pipeline processing (CPP) principle, which guides the proposed parallel ATPG to preserve the task processing orders that are necessary to ensure ATPG determinism but with low inter-thread synchronization overhead. Furthermore, a multi-round test generation and compaction strategy is proposed to avoid possible test pattern inflation. Experimental results show that CPP-ATPG exhibits close-to-linear speedup for at least up to 12 threads.

  • Current-Based Testing, Modeling and Monitoring for Operational
           Deterioration of a Memristor-Based LUT
    • Authors: T. Nandha Kumar; Haider A. F. Almurib; Fabrizio Lombardi
      Abstract: Abstract This paper presents a method for operational testing of a memristor-based look-up table (LUT) memory block. In the proposed method the deterioration of the memristors (as storage elements of a LUT), is modeled based on the reduction of the resistance range, a phenomenon well known as reported in the technical literature. A quiescent current technique is used to diagnose the memristors when deterioration results in a change of state, thus leading to a fault. In addition to testing, the proposed method can be utilized also for continuous monitoring of the memristor deterioration in the LUT. The deterioration of the memristors is modeled using a simple yet accurate equivalent circuit. The proposed method is simulated using LTSPICE and extensive simulation results are presented for operational deterioration with respect to different features such as LUT dimension, range of memristance and MOSFET feature size. These results show that the proposed test method is highly efficient for testing and monitoring a LUT in the presence of deteriorating multiple memristors.

  • Reliability Analysis of Fault-Tolerant Bus-Based Interconnection Networks
    • Authors: Fathollah Bistouni; Mohsen Jahanshahi
      Abstract: Abstract Multi-processor systems need interconnection networks (INs) in order to make the connection among the processors, memory modules, and nodes. Bus interconnection network is the simplest and least expensive one among all the INs. Therefore, bus network is easily understood and preferred by manufactures for implementation. However, a bus network is inherently a non-fault tolerant and blocking network. To cope with these problems, a solution is to use several buses in parallel on a network. Based on this idea, various schemes can be designed for a bus network: (1) Multiple-bus with full bus-memory connection, (2) Multiple-bus with single bus-memory connection, (3) Multiple-bus with partial bus-memory connection, and (4) Multiple-bus with class-based memory connection. On the other hand, a metric for the efficiency of fault-tolerant systems is its reliability. Although, there is no detailed analysis of the reliability of bus-based networks, this paper presents accurate and complete reliability analysis of bus-based networks to achieve these aims: (1) Determining the most efficient design of bus-based networks in terms of reliability, cost-effectiveness, and blocking issues, (2) Providing new methods for evaluating the performance of bus-based networks.
